Subject: [PATCH 0/2] Remove dead code

This is a rework of part of Stephen's patch [1].

This removes the MMIO exclusivity support that was added as part of an
e1000e bug hunt.

The e1000e driver still uses pci_request_selected_regions_exclusive(), but
there are no callers of pci_request_region_exclusive() and
pci_request_regions_exclusive().  I thought it was cleaner to remove the
whole thing than to leave parts of it in place.  But I could easily be
convinced to leave part or all of this in place if people think it's still
useful.

It also removes SR-IOV migration support, which is completely unused, as
far as I can tell.
